    DIVERGENT IONOTROPIC RECEPTORS -
    Divergent Ionotropic Receptors (IR), members of the IR family of ligand-gated ion channels, are largely species-specific, with low amino acid sequence identity. Expressed in gustatory organs, they are believed to be taste receptors. (Adapted from FBrf0211681).

                The Ir94b gene, one of 44 "divergent" ionotropic receptor genes in D. melanogaster, may have been derived from an ancestral ionotropic receptor gene by retroposition, and in some cases, subsequent gene duplication.
